The diagram below shows the interrelationship between two processes. Arrows pointing in the clockwise direction are shown along a circle. On top of the circle is the label Process A and moving clockwise we see an arrow, the label Oxygen and Glucose, another arrow, the label Process B, another arrow, the label Carbon dioxide and Water, and another arrow point back to Process A. Within which organelle do Process A and Process B occur? Both occur within the mitochondria. Both occur within the chloroplast. Process A occurs within the chloroplast and Process B occurs within the mitochondria. Process A occurs within the mitochondria and Process B occurs within the chloroplast.
